Description
Technical field
The present invention relates to injection mold, more particularly, to a kind of core pulling self-locking mechanism of injection mold.
Background technology
When carrying out core pulling with oil cylinder locking large area product face, the injection pressure in core pulling face is acted on commonly greater than oil cylinder
Pressure is locked, segment difference or flash are generated so as to which core pulling be caused to make a concession, in order to solve this problem, the prior art is mainly using such as
Lower scheme：
1. side of scheme increases an oil cylinder drive and carves tight block to lock this core pulling；
2. oil cylinder self-locking oil cylinder of scheme；
Scheme 3. installs the oil cylinder of enough large-diameters in the case of allowing in spatial position；
Scheme 4. increases latching valve at the oil inlet of existing oil cylinder.
More than four kinds of schemes be respectively provided with following shortcoming：
Scheme 1, which additionally increases an oil cylinder, both increases cost, harsher to die space status requirement, and adds and add
In addition work cost also generates mould strength certain influence, also produce in hyperpraxia and extend manufacture cycle；
The self-locking oil cylinder of scheme 2, although being influenced from other aspects, the price of self-locking oil cylinder is general oil cylinder price
It is 5 to 10 times, even more so as to increase larger cost；
Scheme 3 installs the oil cylinder of enough large-diameters in the case of allowing in spatial position, on the one hand, it is substantial amounts of to occupy mold
Spatial position, and cannot be sure about completely solve the problems, such as it is to be solved, on the other hand, the bigger oil cylinder price of cylinder diameter is higher,
It and can be very high to the piston seal performance requirement of oil cylinder；
Scheme 4 increases latching valve at the oil inlet of existing oil cylinder, very high to the piston seal performance requirement of oil cylinder, simultaneously
The service life of latching valve is not grown, and further, the price of the oil cylinder of high leakproofness requirement is very high.
The content of the invention
For the problem present on, and in view of the vital overall situation of both cost and quality in die industry
Under, the present invention provides following solution：
A kind of core pulling self-locking mechanism of injection mold, it is described including carving tight block, small wedge, Loose core block and driving unit
The small wedge of driving unit drive does the reciprocating motion of straight line, and described carve is provided with through hole on tight block, and it is fixed to be provided in the through hole
Position block, the locating piece can slide along the inner wall of the through hole, be provided with the first groove in the small wedge, and described first
For the locating piece described in /V in through hole, the both sides for carving tight block are each provided with a press strip, are set on the press strip groove
The second groove is equipped with, second groove is provided with pumping for the locating piece described in /V in through hole, described carve below tight block
Pellet is provided with the 3rd groove in the Loose core block, described to carve tight block buckle in the 3rd groove, and described carves tight block
Opposite slide can occur along the 3rd groove with the Loose core block.
Further, the 4th groove is provided in the Loose core block, tight block is carved described in the front end insertion of the small wedge
